Horrifying, yet not completely surprising: a new study has found a link between high consumption of meat and junk food and the onset of early puberty in girls.

According to AOL Health:

“[The] study that analyzed 1,000 girls found that breast development began at an average age of 9 years and 10 months, which was a year earlier than what the results of a 1991 study showed. Researchers added that this also makes them more susceptible to long-term breast cancer risk.

Other scientists from Brighton University found that 7-year-old girls who ate meat 12 times a week were 14 percent more likely to reach puberty by the age of 12 than those who ate meat four or less times a week.”
